Someone recently described this channel as “influencer-led”. This video explains why that label doesn’t really fit. Most of what happens here is building, fixing, breaking, experimenting, and learning – usually involving antennas, towers, contests, or the chain between the radio and the antenna.
I’m not trying to persuade anyone to buy anything. I’m trying to show the process, including the mistakes, so others feel able to have a go themselves. If something I do inspires you to try, build, fix, or experiment – then the video’s done its job.
